Torture and mangle was intended as humor, of course.
I've been using my KQ1 as my daily driver for slightly more than a year. I've not had anything get caught by the wash plate, although it can happen with items such as loose robe ties, very small infant socks, and underwire bras that reasonably shouldn't be put in the machine unless in a mesh laundry bag for delicates. That's not so much a fault of the machine as a matter of adjusting laundry habits to the machine's characteristics.
The wash/rinse action on all cycles is varying combinations of spin-shower (60 RPM) and nutation at speeds ranging from 300 NPM (Heavy Duty) to 150 NPM (Wool & Handwash). Normal & Whitest Whites is 275 NPM. Delicate/Casuals is 225 NPM. Successively-gentler cycles across the panel from left-to-right have more spin-shower time and less nutation. Heavy Duty is more aggressive and is intended for very dirty or large heavy loads ... such as 9 pairs of jeans.
Whitest Whites is largely the same as Normal, but defaults to hot water, has a 5-min longer wash time across the range of soil levels, and a slightly different bleach rinse phase.
Jeans may tangle some but no more than in (I suspect) most frontloaders. Proper loading helps to a degree. If your machine has the Jeans/Darks cycle, it runs at 250 NPM with a spin-shower and nutation profile more akin to Delicate/Casual than Normal, and fills largely through the fresh water inlet to help flush undissolved detergent off the fabric to avoid spotting, or "frosting" as I've heard it called, of dark dyes.
While I can't say from long-term use experience, I don't think there're any notable deficiencies in the drive shaft & pulley, bearings, or motor size. Supremewhirlpol, you experienced trouble in those areas? The basket would have been much better with an integral hub instead of the aluminum(?) pressed-on hub that was used ... but that same problem is still happening with frontloaders that have stainless steel drums and aluminum spiders. As discussed previously, there were several design changes on the Calypso through the production period (similar to what Maytag did with the Neppy frontloaders). A little better defense against splashing over the tub would also been good.
